Wireless M-Bus: Application in the energy industry

The digitization of the energy industry is the basis for smart energy management. Here, a basic building block is the smart recording of heat, water, electricity and gas consumption data. which requires a modern measuring technique and corresponding transmission technologies. One such technology is the wireless Meter-Bus (wM-Bus), which allows for the central reading of all consumption data almost in real time. In this article, we focus on the use of transmission technology in the energy industry, in particular for submetering.

Wireless M-Bus: Introduction and functioning

The M-Bus, abbreviated for Meter-Bus, is a technical standard for the transmission of measurement data, which exists in both wired and wireless specifications. Wireless M-Bus installations can collect and transmit data from up to 250 sensors, being mainly used in consumption data acquisition. In this article, we explain the functioning of the wireless M-Bus communication.

Application fields and relevance of mobile applications in the construction industry

In the recent decades, mobile communications have gained a lot of importance, not only in the private sector, but also in the industry. Mobile applications allow for data acquisition, digitization, and automation of industrial processes. In the past few weeks, we have already occupied ourselves with general application areas in the Industry 4.0 and specific case studies from the energy industry. In this article, we want to take a closer look at the construction industry and discuss the relevance of mobile applications in this particular industry, as well as several specific case studies.

Application fields and relevance of mobile applications in the energy industry

Our society and economy depend on a permanent and reliable energy supply. Therefore, this represents a critical application, which requires a secure communication. In the recent decades, mobile communications have gained a lot of importance, not only in the private sector, but also in the industry. Mobile applications allow for data acquisition, digitization, and automation of industrial processes. The energy industry also benefits from this. In this article, you will discover which applications are used for the power supply and which progresses could 5G offer.

Application fields and relevance of mobile applications in the industry

In the recent decades, mobile communications have gained a lot of importance, not only in the private sector, but also in the industry. As the drive of the so-called “Fourth industrial revolution”, it lays the foundation of the implementation of Industry 4.0. Mobile applications allow for data acquisition, digitization, and automation of industrial processes. Machine learning and artificial intelligence are also increasingly used in the industrial context. In this article, we will clarify the different mobile-based transmission technologies, what is the potential of 5G when it comes to applications in Industry 4.0, and delve into some application examples.

SigFox

The networking of intelligent devices is becoming increasingly important in the private sector, as well as in the industry. One of the most important networking technologies for this is SigFox, developed by the telecommunications company with the same name. Like LoRaWAN, SigFox uses the unlicensed frequency spectrum. The technology distinguishes itself through a particularly long battery life and reduced installation and operation costs, and it is used, for example, in the logistics sector, for the monitoring of deliveries. In this article, you will find more detailed explanations on functioning, application, and differences from other transmission techniques.

LoRaWAN – Low Power Wide Area Network

, ,

In the last two blog posts, we have talked about the common mobile-based transmission technologies for IoT applications. In addition to LTE Cat. M1 and NB IoT, there are also other technologies, which use the unlicensed frequency spectrum for the data transmission. The main advantage of such networks lies in the elimination of license fees and contracts with mobile network providers. One of the common technologies which takes advantage of the unlicensed frequency spectrum is LoRaWAN. In this article, you will discover how this technology functions and why is suitable as network for IoT applications.

LTE NB IoT – Narrowband Internet of Things

, ,

The use of cellular-based technologies is widespread for the networking of smart devices. In addition to LTE Cat. M1, the Narrowband Internet of Things (NB IoT) is also available. This is designed to transmit even smaller data volumes and has higher latency times than LTE Cat. M1. Thus, NB IoT is less suitable for the transmission of time-critical data, but it has its own advantages, such as the higher battery life and lower costs. In this article, you can discover how the mobile communications technology functions and for what applications are its features beneficial.

LTE Cat. M1 – Long Term Evolution for Machines

Billions of smart devices worldwide, both in the industry field and in the private sector, are already connected to a sensor network. The Internet of Things has become indispensable. The so-called Low Power Wide Area Networks support the connection of these smart devices. LTE Cat. M1, also known as eMTC, represents such a supplementary standard, which convinces, among other things, with its particularly high network coverage.
